Catalytic transfer dehydrogenation of silyl protected amines, requiring sp3 CâH bond activation, is mediated by a bridging arene complex of the type [(Cp*Co)2-μ-(η4:η4-arene)] under mild conditions. Mechanistic and qualitative rate studies establish the compound as a more reactive Co(I) source when compared to other known Cp*Co(I) complexes.
在温和条件下,需要激活sp3 C-H键的
硅烷保护胺的催化转移脱氢反应由[(Cp*Co)2-μ-(μ4:μ4-arene)]类型的桥连
芳烃络合物进行。机理和定性速率研究证实,与其他已知的Cp*Co(I)络合物相比,该化合物是一种反应性更强的Co(I)源。
